Product Name

Underground Utility Warning Tape 365m x 100mm – CAUTION WATER PIPE BELOW – Blue LLDPE

Overview

Reduce the risk of accidental water service strikes and avoid leakage, reinstatement costs, and site delays with Underground Utility Warning Tape. Manufactured from rot-resistant Linear Low-Density Polyethylene (LLDPE), this non-adhesive marker tape provides a clear visual warning to excavators before tools reach the buried service. Supplied as a large 365m roll with a 100mm width, it supports high visibility and long trench coverage for utilities, civils, highways, and groundworks projects.

Key Features & Benefits

  • High-visibility blue tape with bold “CAUTION WATER PIPE BELOW” legend for fast on-site recognition.
  • Colour coded in accordance with NJUG guidelines to clearly identify water services.
  • Rot-resistant and acid-resistant LLDPE construction helps keep the message intact and legible underground.
  • Non-adhesive design intended for loose placement in trench backfill, not stuck to pipes.
  • Acts as an early-warning visual barrier when installed approx. 300mm above the buried service line.
  • Helps reduce costly leaks, service outages, and reinstatement works caused by accidental strikes.

Installation & Applications

Suitable for utilities, civils, highways, and groundworks projects involving buried water pipes. For best practice, do not lay the tape directly on the pipe. Backfill the trench to approximately 300mm above the service line, lay the tape loosely along the trench length, then complete the final backfill to ground level. This ensures excavation tools encounter the warning tape first.

Who Is This For?

  • Excavation and groundworks crews working near buried water services.
  • Utilities contractors installing, repairing, or maintaining water networks.
  • Civils and highways teams marking services for safer future excavation.
  • Site managers and procurement teams specifying trench safety and service identification.

Competitive Advantages

This professional-grade warning tape combines clear water service identification with durable LLDPE construction, making it ideal for long trench runs where dependable visibility and consistent service marking reduce risk and rework.

Frequently Asked Questions

What is underground utility warning tape used for?
It is used to visually mark the route of buried water pipes so excavators receive an early warning before tools reach the service.

How deep should the tape be installed?
Best practice is to install it approximately 300mm above the buried service line so excavation equipment encounters the tape first.

Should the tape be placed directly on the pipe?
No. It should be laid above the service line so it provides a warning before contact with the water pipe.

Is this tape adhesive?
No. It is a non-adhesive marker tape designed to be laid loosely in trench backfill.

Will it last underground long term?
Yes. The rot-resistant and acid-resistant LLDPE construction helps keep the tape intact and legible for long-term service marking.

Are other utility variants available?
Yes. This range typically includes versions for gas, electric, fibre optic, telecoms, sewer, street lighting, and traffic signals using industry-standard colour coding.
